Since the DSLR Revolution the Leica R primes have been the pinnacle of quality hybrid photo-cine prime lenses. Duclos Lenses has applied their Cine-Mod® to thousands of Leica R primes which brought a seamless focus gear, smooth click-less aperture, common 80mm front rings and Canon EF mount. But we had never tackled the PL mount solution. There were a couple of Chinese modifications that brought PL mounts and larger, heavier housings to the R series. But it wasn’t until Cinescope teamed up with TLS in the UK to bring a proper, robust cine-style housing to the Leica R primes. Continue reading Leica R Primes Done Right by Cinescope and TLS.

The increasing popularity of Fujifilm’s cameras for quick, nimble motion picture work has begun another trend in the mirrorless realm – using legacy legacy lenses for cinematic work. Similar to the popularity of the Sony E-mount ecosystem, the X-mount features a similar shallow flange depth that makes adapting older SLR lenses a breeze with a plethora of cheap, accessible adapters. But what if you wanted an affordable, purpose built cinema lens for the X-mount system without using cheap, flimsy adapters? Continue reading Fuji X-Mount for Veydra Mini Primes Coming Soon

I’ve written about the Tokina 11-16mm many, many times. In fact, I was temporarily banned from REDUser years ago for backhandedly plugging the Duclos 11-16mm conversion – breaking the rules of the forum. I’ve since cleaned up my act (sort of). I speak often of the Duclos 11-16mm, and when I do, I always give credit to Tokina for making such a great product. I wanted to take a post here and acknowledge the original lens, it’s heritage, influence, and evolution over the past (nearly) decade. Continue reading Tokina’s Gateway to Cinema: The 11-16mm

Everyone should be familiar with the price of equipment sporting a small red dot. In this particular case, the red dot is pretty large. A venerable cream of the telephoto crop, this set consists of a Leica APO-Summicron-R 180mm f/2.0, a Leica APO Telyt-R 280mm f/2.8 and finally a massive Leica APO-Telyt-R 400mm f/2.8. The set is currently owned by Samy’s Camera – but not for long as it’s being sold for $100,000.00. This is no ordinary set of rare Leica telephoto primes. Custom modified with PL mounts and integrated focus and iris gears by Duclos Lenses, this is a one-of-a-kind set making the rare even rarer.

A view of the Leica 280mm f/2.0 PL mount and iris ring.

About two years ago I was paid a visit by some fellow named Samy who claimed he was from Samy’s Camera. It took me a few seconds to realize he wasn’t just some guy from Samy’s… He was Samy’s. Samy proceeded to explain what he wanted done to these lenses, at which point I gave some examples of what something like this costs and the down-time associated with custom modifications. You see, performing this type of work isn’t something that we here at Duclos Lenses do for just any lens. There are several prerequisites for this type of work that we stick to pretty closely which usually discourage customers from advancing with bespoke engineering. The most important condition is quality. We don’t design or engineer anything that we aren’t confident putting our name on, abel to admire once completed and say “damn… that’s marvelous”. The second most important factor is the cost. I understand that there are some individuals out there that simply don’t care about the cost, and want, need, must have something despite the fee. This entire process requires a balance of these two primary factors (quality/cost) which I felt Samy understood and shared in our enthusiasm. As a result of our unrelenting crusade for precision and quality, custom conversions go through many stages within Duclos Lenses beginning with conception and going on to design, engineering, prototyping, manufacturing, and finishing.

You can’t have such nice lenses and not provide appropriate protection. The set comes with custom foamed travel cases.

Over the next few months we penned, plotted, rendered, caffeinated, and repeated many times over. The final result was a set of three Leica telephoto primes with stainless steel PL mounts, integrated focus and iris gears, and industry standard supports, ready to deliver to Samy. As far as I know, at the time, Samy had no plans to offer these lenses to anyone because of their rarity but I’m glad to see that they are for sale and possibly going on to shoot stunning images. I hope that whoever ends up purchasing these lenses lets me know so that I can keep an eye on them over time. It’s this desire to follow bespoke projects throughout their life, that I feel makes the work that I’m involved with special. If you’re interested in purchasing this set, check with your accountant/wife and then head on over to the eBay listing.

Duclos Lenses has developed a conversion process for the Canon Cinema Eos CN-E Primes that provides a high quality, stainless steel PL mount that allows the primes including the 14mm, 24mm, 35mm, 50mm, 85mm, and 135mm to be used with any PL mount camera.

Canon introduced their pair of lightweight zooms, 15.5-47mm and 30-105mm, about a year ago and they’ve had a bit of a rough start. They were introduced into an already saturated market where every other manufacturer had been making zoom lenses for decades. Canon is no newb when it comes to high-end cinema zooms. They had their line of S16 format zooms a few years back (remember 16mm film?) that were adapted from their long running and still successful video lens division. Everyone knows that Canon makes great lenses. Their L series is a perfect indication of high quality, professional glass. But in the recent past, there wasn’t really any professional cinema lens offerings from Canon. The new lightweight zooms were an excellent comeback! They had all the features I look for in a zoom lens. They are designed with simple, robust components throughout the lens. Plenty of focus marks on clean, simple barrels. Consistent T-stop of T2.8 throughout the zoom range. And just about every other feature of a professional cinema zoom lens. Continue reading Canon Lightweight Zoom Universal Mount From Duclos Lenses

This post is part of a series of upcoming reviews of camera-lens mounts and their pros and cons. Quite possibly the most common camera-lens mount on the market today is the Canon EF and EF-S mount. Introduced in 1987 and updated in 2003, the EF-S mount added several features that improved on the original FD Mount including focus motors placed inside the lens to enable auto-focus. Step forward 2.5 decades and the Canon EF and EF-S mount are the reigning champion of still photography and quickly gaining popularity in the world of cinema. For the sake of simplicity, I’ll simply refer to the Canon mount as EF instead of EF or EF-S. If you need more clarification on the difference between EF and EF-S, google it. 😉

Yes. But not really.

The PL mount is an excellent standard that Arri gave us several decades ago and has been the industry standard alternative to Panavision’s camera mount ever since. The PL (Positive Locking) mount is large enough to accommodate sizable rear elements and strong enough to support the largest of professional cinema lenses (with proper support of course). More and more cinema is moving over to Nikon F, Canon EF, and even the Micro 4/3 standard. So why is everyone trying to slam a PL mount on their grandfathers old set of Nikon AIS lenses? It’s simple. All three of the still photo mounts I mentioned have their limitations that can really disrupt a cinematographers flow. For example, Nikon, Canon, and M34 all have a locking pin that keeps the lens set in it’s place and you push the little button to release the pin. Most of those camera mounts have a very weak leaf spring that keeps a bit of pressure on the lens mount to stabilize the lens. Certainly not as much pressure as PL mount fully tightened. Still photo mounts usually have one position that the lens attaches to the camera in and that’s it. you can’t rotate the lens relative to the camera whereas PL mount, depending on the lens manufacturer, can have up to four mounting positions, each 90 degrees apart. Not a deal breaker but still just another reason PL is superior for cinema. I can go on all day about the benefits of PL mount over Canon or Nikon mounts but that wouldn’t help many people. Continue reading Canon EF to PL, Is It Possible?

The DSLR Revolution is in full swing at the moment and everyone is scrambling to get the glass they love on the camera they are stuck with. It doesn’t sound too difficult to simply change a piece of metal, but there are a lot of things to consider when attempting to change a mount. After-all, lenses are a precision tool, naturally. Lens and camera manufacturers all have their own mount system which specifies a flange depth, the distance from the mount flange to the film/sensor plane. When this number is accurate, the image that the lens produces falls on the sensor in perfect focus. Move it forward or backward by the smallest amount (.0005″) and your collimation will be completely off, throwing out your focus marks and destroying the accuracy of a lens, especially a zoom lens. All of the different SLR camera manufacturers had a similar theory and design, but just slightly different numbers for the flange depth. Wouldn’t it be great if they all agreed on a standardized mount that would allow any lens to be used on any camera? Yeah, it would be great. But that’s not how it works.

We’ve been building our 11-16mm lenses as quick as we can while still maintaining the highest quality standards we can. We’ve received great feedback from a lot of satisfied customers and look forward to continuing to fill orders. There are quite a few back-orders still but rest assured, we are working diligently to fill orders as quickly as possible. This particular photo is our Nikon-F mount model. We offer the lens in PL, Nikon-F, and Canon-EF. Such a versatile little beauty. 🙂

Zeiss recently announced that they will be utilizing the Micro Four Thirds standard on their sought after CP.2 Compact Primes. This will come in the form of an interchangeable mount in addition to the existing Nikon F, Canon Eos, and PL mount. The Micro 4/3 mount will allow the cinemaesque CP.2s to be used on the popular Panasonic AF-100 camera instead of adapting the Nikon, Canon, or PL mount. Just another example of Zeiss keeping up with the latest and greatest. The CP.2 lenses have an optional support hole on the bottom of the lens that I would strongly suggest utilizing since the Micro 4/3 mount is very fragile compared to a PL mount. I certainly wouldn’t suggest relying on only the Micro 4/3 mount to support a lens as heavy as a CP.2.

Before you get too excited, a “universal mount” in the motion picture industry is not universal. The universal mount is what is used on lenses such as the Cooke 20-100mm or 25-250mm, and more recently on the Angenieux 24-290mm. It’s simply a sub-mount with a threaded rear that allows several different mounts to be attached, most commonly a PL or Panavision mount. These were fairly common on professional zoom lenses in the 80s, 90s, and 00s. Now, wouldn’t it be awesome if you could put a classic Cooke 25-250mm on a Canon 7D? Yes. Yes it would be awesome. Please observe the awesomeness:
